I am having an issue with the formatting of my webpage. I am using both telerik:RadButton and telerik:RadPanelItem on my web page. They have been working fine until now when I am trying to change the skins on both tools. Before I changed them they were both Web20 but I want to change the RadPanel skin to Windows7 and RadButtons skin to Telerik. When I look at the webpage in IE10, Chrome, and Firefox the page shows both the new skins, but when I look at the page in IE8 and IE9 the RadPanel disappears and the format is gone. I have tried other skins for the RadButton but have not been able to get anything to work except if I go back to what I was doing before with having both items using the Web20 skin. Any ideas on why this is happening?
